We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
CHAPTER IV
Making 16-Mm Originals
Size of Originals for 16-Mm Release Prints
As mentioned earlier, 16-mm release prints may be manufactured from a variety of different film sizes as originals. Dimensions have been standardized to the point where it is possible to make 16-mm release prints from three sizes of picture (35-mm, 16-mm, and 8-mm), and from either of two sizes for sound (35-mm or 16-mm). Up to the present there is no commercially satisfactory 8-mm sound available.
The greatest volume of release prints has been produced by optical reduction from duplicates of 35-mm originals. Since the production of 35-mm films has been described at some length in other texts and in engineering journals, such as the Journal of the Society of Motion Picture Engineers, such data will not be repeated here.
A smaller yet important volume of release prints has been produced from 16-mm originals. Kodachrome has played an important part in encouraging 16-mm growth for industrial, education, and other non-amateur purposes; no integral tri-pack color film of this kind has been available for equivalent 35-mm use. The combination of 16-mm Kodachrome picture with 35-mm negative sound track has been fairly common, but the inconvenience of handling 35-mm film (which is inflammable as well as clumsy) simultaneously with 16-mm film (which is compact and slow burning) will mitigate against further rapid growth — especially when 16-mm sound-recording apparatus of good reliability becomes more widely available in the near future.
While 8-mm picture has often been used for special purposes to provide 16-mm release prints, such use is the exception rather than the rule. The emphasis of war standardization concentrated heavily upon 16-mm, and it is only logical to expect that such standardization will have farreaching effects in further expanding the use of the 16-mm size. Rapid improvement of quality in 8-mm picture and very wide amateur use can be reasonably expected, but the far lesser extent of 8-mm standardization compared with that of 16-mm will act as a handicap in its growth for professional uses.
